+We want to fix all the issues as soon as possible, but before fixing a bug, we need to reproduce and confirm it. In order to reproduce bugs, we ask that you provide a minimal reproduction scenario (GitHub repo or failing test case). Having a live, reproducible scenario gives us a wealth of important information without going back & forth to you with additional questions like:
 
 - version of Webpack used
 - version of the loader / plugin you are creating a bug report for
 - the use-case that fails
 
 A minimal reproduce scenario allows us to quickly confirm a bug (or point out config problems) as well as confirm that we are fixing the right problem.
